Stereotactic body radiotherapy (SBRT) has emerged as an effective and safe treatment for low and intermediate-risk prostate cancer(PCa). However, there is no study that has investigated the effectiveness and safety of SBRT with pelvic radiation and gross target volume(GTV) boost for high-risk prostate cancer patients yet. The investigators designed a phase II clinical study of SBRT with pelvic radiation and GTV boost based on mpMRI in patients with high-risk prostate cancer.

The radiation dose to the primary tumor was 40 or 45 Gy in five fractions according to the clinical determination of the radiologist. The dose to the positive lymph nodes and the prostate and seminal vesicles was 37.5Gy in five fraction. And internal iliac, external iliac, obturator, and presacral pelvic drainage regions received 25 Gy/5f, simultaneously. The treatment was delivered every other day. The volumetric modulated arc radiotherapy (VMAT) or intensity-modulated radiotherapy (IMRT) was used to complete treatment. Image-guided radiotherapy(IGRT) was performed for every treatment.

patient-reported quality of life
patient-reported quality of life using European Organization for Research and Treatment of Cancer Quality-of-Life-Questionnaire-Core-30(EORTC QLQ C30) .The The minimum and maximum values of EORTC QLQ C30 are 0 and 100,respectively.Higher scores for functional and overall health areas of EORTC QLQ C30 indicate better functional status and quality of life, and higher scores for symptom areas indicate more symptoms or problems.
Time frame: three months
symptom score
Symptom score using the International Prostatic System Score (IPSS) .The minimum and maximum values of IPSS are 0 and 35,respectively.A higher score of IPSS means a poorer quality of life.
Time frame: three months
